most frequent in shady, more moist spots, often in deep woods. The 
remaining two species are easily distinguished from the two men- 
tioned above by the margins of the leaves, which are thin and mem- 
branaceous, and are folded in over the central portion of the leaf, as 
illustrated in o, o’ and p.” 
I can not too strongly commend “Mosses with a Hand-Lens” 
(price $1.10) prepared with the purpose of giving “by drawings and 
descriptions the information necessary to enable any one interested 
to become acquainted with the more common mosses with the least 
possible outlay of time, patience and money.” The book contains a 
key to the genera based mainly on structural characters and one 
mainly on habitat, also many keys under the genera; copious illus- 
trations, clear and accurate on almost every page of the text and 
eight full-page plates from drawings by Mary V. Thayer; and an il- 
lustrated glossary of bryological terms. 
MEETING OF THE BIOLOGICAL CLUB. 
The Biological Club met in Zoological lecture room December 3, 
1900. Prof. Herbert Osborn presided, twenty-six members present. 
The following papers were presented : 
“ Notes on the Saw Brier, and a Rhanmus new to Ohio.” 
“The Waverly Series of Ohio.” 
In the first paper Prof. Kellerman spoke of the distribution of 
tire Saw-Brier, Smilax glauca , in the southern part of the State, and 
exhibited specimens showing its striking variations in form of leaves. 
The southern buckthorne, Rhamnus caroliniana , was observed 
commonly in Adams County. It also occurs in Brown County. This 
is the first record for this species in Ohio. Specimens in fruit were 
exhibited. 
A hackberry was found unlike any form hitherto reported from 
Ohio. Specimens are in the hands of Rev. E. J. Hill for study and 
determination. 
Prof. Ball reported leaf variation as occurring commonly in Colo- 
rado, and that various leaf forms could be observed in climbing a 
single hill. 
Prof. Prosser, in the second paper, reviewed the literature that 
has been published on the Waverly Series of Ohio, and as a summing 
up gave a list of names with authorities to be used in future in 
speaking of the formations of this series. These are as follows: 
Beginning above the Huron Shale. 1. Bedford Shale (Newb.) 
85 feet. 2. Berea Grit (Newb.) 40 feet. 3. Sunbury Shale (Hicks) 
10-15 feet. 4. Cuyahoga Shale (Newb.) 275-300 feet. 5. Black Hand 
Conglomerate (Hicks) 40-100 feet. 6. Logan Sandstone (Andrews) 
115 feet. 
Under the head of personal observations, Prof. Schaffner gave a 
list of trees and shrubs which he and F. J. Tyler had found cutting 
off (self-pruning) their own branches. 
Prof. Kellerman remarked upon the abundance of the red- 
seeded dandelion in various parts of the state. 
Walter Metz, J. A. Beer, H. A. Clark, Charles 1. Meade, Miss 
Elizabeth Sessions, Miss L. D. Wilson, W. P. Simpson, Mrs. J. H. 
Schaffner, B. B. Wells, Mrs. E. D. Ball, J. N. Frank, A. G. McCall, 
Miss Carrie R. Weick, A. C. Whitmore, Miss Caroline Meade and 
Miss Maud Flynn were elected to membership. 
Professors Prosser, Landacre and Mr. Griggs were appointed a 
committee to locate board and lodging for members of the Ohio 
Academy of Science. Adjourned. Jas. S. Hine, Secretary.
